A.3 Bridge Point-to-Multipoint (BPM) Operation
The Advanced VSAT BPM feature functions as a Learning Ethernet Switch when the “Working
Mode” is set to BPM. This makes the Advanced VSAT equipment appear as a “Sky Ethernet
Switch” and allows for a greatly simplified network deployment.
In BPM Mode, all L2/L3/L4 protocols such as VLAN, MPLS, IPv6, OSPF, and BGP will flow through
the network as they would through an off-the-shelf Ethernet Switch.
The Advanced VSAT System, running in BPM Mode, supports Flat Networks, Flat Networks with
Routers, and VLAN Trunking network topologies.

A.4 E1 WAN/RAN Optimization
E1 RAN (Radio Access Network) Optimization technology, jointly developed by Comtech EF Data,
CEFD sister division Comtech AHA Corp., and CEFD subsidiary Memotec Inc., is used to
significantly reduce the Wide Area Network (WAN) / satellite bandwidth required to carry an E1
bearer used for cellular backhaul. It is a feature available with the CDM-840 and ODM/R-840
Remote Routers and the CXU-810 RAN Optimizer.
